MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 712,276, dated October28, 1902.

Application filed June 30, 1902.

To all whom it may concern:

Be it known that I, HENRY EDMoNDs, manufacturer, a subject of the Kingof Great Britain, residing at 60 Te nby street, north, in the city ofBirmingham, England, have invented certain new and useful Improvementsin Mechanical Movements, of which the following is a specification.

This invention consists of the hereinafterdescribed improved mechanismfor imparting reciprocating or sliding movements to rotating shafts,spindles, and such like from their own rotation, such mechanism beingparticularly applicable to the shafts of shaking or rumbling barrels andbutter-making churns.

In the accompanying sheet of drawings the invention is illustrated asapplied to a shaking-barrel shaft, andthe mechanism and its working willbe hereinafter clearly described in connection therewith.

Figure 1 of the drawings is a side elevation showing an arrangement ofthe improved mechanism for twoshaking-barrels worked off one shaft, themechanism being particularly suitable for heavy work. Figs. 2 and 3 aredetail sections of parts of the mechanism, Fig. 1, upon the lines A Band O D. A diagram is shown in Fig. 4 of the mechanism, Fig. 1, inanother position during working.

In Figs. 1 to 4, do are the shaking or rumbling barrels, and a the shaftcarrying them, the said shaft being suitably supported in bearings torotate and slide. Parts ofthe bearings are represented by theplumberblocks a a on fixed frames or a the otherbearing parts not beingshown in the drawings. The shaft a is rotated by the beltpulley c orother device rigidly fixed upon it. Fixed upon the shaft a between theblocks a a is an eccentric or an eccentricallymounted disk d, over oraround which a detachable strap 01 freely works. To this strap, at 6 isjointedly connected the forked ends 6 e of a connecting-link e, whoseother end 6 is coupled to the one arm f of a bell-crank leverf,hereinafter defined,'in such a manner that the said other end can, inaddition to turning upon its center pin 6 wabble or have an amount offree play laterally. The bell crank lever f, which is practically astrongly-built rocking frame, is jointedly Serial No. 113,879. (Nomodel.)

connected at f to a pair of'parallel-swinging links g, fulcrumed at g'to one of the stationary frames 0. the said swinging links giving tothe bell-crank lever or frame f a shifting fulcrum or joint for thepurpose hereinafter defined. The one arm f hereinbefore mentioned, ofthe rocking frame f is forked, as shown in Fig. 2, and serves toefiectively couple the link 6 to the said frame, while the other arm fwhich is also forked at its said swinging frame f with a sleeve-likepiece or bush h, freely encircling the shaft a beendf jointedly andeffectively connects the tween two thrust or abutment collars 2' i saidframe, this rocking or oscillation having the effect of sliding theshaft a with the parts it carries, to and fro within the plumberblocks aa and other bearings, (not shown,) it being understood that thebelt-pulleys or other part c, from which the whole movement of the shafta is obtained, slides along with the said shaft. Acomparison of theposition ofthe parts in Fig. 1 and in the diagram Fig. 4 will show thatin the first case the shaft, with the shaking-barrels upon it, has beenslid from right to left and in the second case from left to right. Theswinging links g in the rocking movement of the frame f compensate forthe are through which the shafts and spindles which are themselves theparts rotated and requiring reciprocation as, for instance, the shaftsor spindles of churns for butter-making-the essential features of themovement being the simple upand-down movement of the link 6 from theeccentric crank or the like to rock the swinging frame f.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

1. In a mechanism of the character specified, the combination of ashaft, means for rotating said shaft, a link, means operated by saidshaft for imparting a reciprocating movement to said link, a rockingframe connected to said link, a movable fulcrum for said rocking frame,and means for imparting the movement of said rocking frame to saidshaft.

2. In a mechanism of the character specified, the combination of aslidably-mounted shaft, means for rotating said shaft, an eccentric onsaid shaft, a link operated by said eccentric, a rocking frame pivotallyconnected to said link, a movable fulcrum for said rocking frame, andmeans for imparting the movement of said rocking frame to said shaft.

3. In a mechanism of the character specified, the combination of aslidably-mounted shaft, a plurality of supports for said shafts, meansfor rotating said shaft, an eccentric on said shaft, a link operated bysaid eccentric, a rocking frame pivotally connected to said link, a linkconnected to one of said shaft-supports and serving as a movable fulcrumfor said rocking frame, a loose sleeve on said shaft, means forpreventing longitudinal movement of said sleeve on said shaft, andaconnection between said rocking frame and said loose sleeve.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

HENRY EDMONDS.
